A Correct answer
Explanation

Generally, short daily exposures of about 10 to 15 minutes of direct sunlight on the face, arms, or back without sunscreen are sufficient for the skin to produce adequate Vitamin D. Longer periods like 2 hours per day or 5 hours per week are unnecessary and increase the risk of skin damage.
